Given numbers are 642,636,495,677,330

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 642,636,495,677,330 is 7601748660.

Find LCM of 642,636,495,677,330 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 11 x 107 x 106 x 1 x 677 x 3 = 7601748660

Therefore, the lowest common multiple of 642,636,495,677,330 is 7601748660.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

642 x 636 x 495 x 677 x 330 = 45154387040400

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

642 : 1, 2, 3, 6, 107, 214, 321, 642

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

677 : 1, 677

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,636,495,677,330, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

636:2x 2x 3x 53

495:3x 3x 5x 11

677:677

330:2x 3x 5x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 3x 5x 11 = 5940

Therefore, the value for common factors is 5940.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 45154387040400/(1x5940)

LCM = 45154387040400/5940

LCM = 7601748660

Thus, we can understand that the LCM of 642,636,495,677,330 is 7601748660.
